Application filed June 13,

My invention relates to paper making machines, and especially to machines known as cylinder type machines.

One of the objects of the invention is to provide a simple and practical construction of machine of the class specified.

Another object of the invention is to arrange for the advantageous application of suction to the cylinder and also to arrange for the ready adjustment of the pressure of c same as desired.

Another object of the invention is to arrange tor the withdrawal of water from cylinder by suction. l

Another object of the invention is to permit independent regulation of the suction for forming and dryin the paper on the same cylinder and for withdrawing the water.

In the accompanying drawings, lFig. 1 is a longitudinal section of a paper making machine embodying my invention; l

Fig. 2 is a plan view ot same.

Referring to the drawings, I show a rotary cylinder 1 having a perforate cylindrical wall adapted for forming paper.

The cylinder 1 is mounted on a fixed tubular shaft 3, supported at its ends by pedestalsI 4 and 5. Shaft 3 has upstanding tubularv members 6 6 and downwardly extending members 77. The former are for exhausting airfrom the upper part of the cylinder 1 to 'form and dry the paper. The latter (members 7 7) are for exhausting air from the lower part of the cylinder for withdrawing water therefrom-water which is with drawn from t-hepulp` material in the formation and drying of the paper.

The tubular members 6-6 are connected with the upper longitudinal section or compartment 9 of shaft 3; the members 7-7 with the lower compartment 10 thereof. Compartment 9 is connectedA with chambers 11 and 12 in pedestals 4 and 5, and compartment 10 with chambers 13 and 14 in same.

Air pipes 15 and 16 are connected with chambers 11 and 12 respectively. Air pipes 17 and 18 are connected with colnpartments 13 and 14, respectively. Air pipes 15 and 17 are preferably connected together, as are 16 and 18, and all run to a suitable suction pump 20. Pipes 15, 16, 17 and 18 are provided with Valves 21, 22, 23 and 24, respectively, so that air pressure in each pipe may be independently regulated. Water dis- 1923. serial no. @45h28.

charge pipes 25 and 26, extend from cham.

bers 13 and 14, respectively, and are connected to a suitable pump 27, which is also connected with a head box 28 for supplying papermaterial to cylinder 1. A plate or box, (not shown) is located within cylinder 1, opposite the apertures therein, between the take-od of the paper and thel point of applicatlon of the pulp, to prevent air from entering and destroying the vacuum.

In operation, paper materialis fed from head box 28 to vat 29 containing `cylinder 1, so that such material may be applied to the lower portion of cylinder for forming paper thereon. rlhe arrangement for doing this is shown in my copending application Serial No. 630,484, filed April 7, 1923, and is not described herein as ity forms no. part of my present invention. The paper material adieres to the cylinder as same revolves, being formed thereon and dried by the suction in upper part of cylinder controlled by pipes (5*6. The water withdrawn from paper material drops to the bottom 4of cylinder and is lifted by suction of pipes 7-7 and `siphoned into compartments, 13A and 14, whence' it is withdrawn by pipes 25 and 26 and then returned to head box 28 for further use.

Ordinarily air pressure in 10, 13 and 14 is reduced somewhat more than in 9, 11 and 12, so as to secure the proper action. Regulation of pressures may be secured by valves 21, 22, 23 and 24.

lln this way, water is automatically removedxby suction, as well as paper being formed by same, and consequently the suction apparatus usedor forming and drying paper on cylinder may also be used for withdrawing water. The water drawing suction may also to some extent, and ,under certain circumstances, assist in withdrawing water from paper material.

lt will be `understood that changes and modiiications may be made without departing from the spirit of the invention.
